Description

BACKGROUND

User interfaces for computing devices are often rigid and complex. Users may be required to navigate multiple layers to perform a task, record thoughts, organize information, or access content. Current user interfaces typically lack the flexibility and ease of use available with a simple analogue journal. As a result users often still rely on pen and paper for unstructured writing, sketching, note taking, and calendaring in everyday life. Users may also spend time copying and/or translating information form a paper-based format into a digital form, for example, by inputting the information into a computing device.
US 2002/0114516 A1 discloses a handwriting recognition input system including a handwriting input area and a plurality of activatable controls. Each activatable control is associated with a different reference library, and each is adapted to recognize characters input on the handwriting input area as belonging to the associated reference library. A method for handwriting recognition is disclosed which includes the steps of selecting at least one character set from among a plurality of character sets and recognizing at least one character using the at least one selected character set.

SUMMARY

Touch sensitive computing devices and methods are provided, as defined by the appended claims.

DETAILED DESCRIPTION

Fig. 1 is a system diagram illustrating a freeform interaction architecture 10 that may be used with a computing device 12. The architecture 10 includes modules. The modules may be software modules that may reside in a memory 11. A processor 15 may be configured to execute the software modules. The architecture 10 utilizes a touch sensitive display 14 configured to receive a touch input 16 on, for example, a surface 18 of the touch sensitive display 14. A graphical user interface 19 may be configured to provide various features to help a user provide input to the computing device 12, and/or to provide feedback and information to a user. The graphical user interface 19 may be coupled with the software modules via a GUI module 21.
The touch input 16 is illustrated here with a generally oval shape in dashed line. A gesture recognition module 20 is coupled with the touch sensitive display 14, and configured to receive the touch input 16, and to determine, based on the touch input 16 and by selecting from a plurality of predefined freeform gestures a recognized gesture 23, also shown with the generally oval shape in dashed line. The gesture recognition module 20 may be included as part of a touch input recognition module 22. A personal information management (PIM) module 24 is coupled with the gesture recognition module 20. The PIM module 24 includes a PIM database 26. The PIM module 24 is configured to apply a selected item 28 shown on the touch sensitive display 14 to a selected one of a plurality of different PIM schemas 30 of the PIM database 26. The selected one of the PIM schemas 30 is selected based on the recognized gesture 23. In some cases, when the selected item 28 is applied the selected item 28 may also be saved in a mass storage 36. The plurality of PIM schemas 30 include one or more of a calendar item 44, a task item 46, and a contact item 48. Other PIM schemas 50 may be included. Note, in some cases, as when the selected item 28 includes markings made by a user, the touch input 16 may generally be considered to include both the selected item 28 and the gesture made with an input device 17. In this illustrated example the touch input 16 may be considered as being made after the selected item 28 is present. It will also be understood that the selected item 28 may be from various forms of input.
A character recognition module 52 is configured to recognize alphanumeric characters included with the selected item 28 upon recognition of the recognized gesture 23. The character recognition module 52 is also configured to cause the PIM module 24 to save the alphanumeric characters into the PIM database 26 as a searchable item. The character recognition module 52 may also be configured to cause the alphanumeric characters to be saved in the mass storage 36.
In some examples, the touch sensitive display 14 may be configured to display the selected item 28 on the touch sensitive display 14 within a journal page graphic 31. As mentioned, the selected item 28 may be the result of an earlier touch input 16 made with the input device 17. Various objects may serve as an input device, such as a pen, or a stylus, or a finger, or the like. The input may be, or include anything that may be possible to add to a piece of paper with, for example, a pen, or a pencil. For example, without limitation, markings such a drawing, a doodle, a note, an address, numbers and the like. In addition other items may be included such photos, or digital documents, and the like. The other items may be, for example, without limitation, inputted into the computing device 12, created by the computing device 12, or retrieved from the mass storage 36.
The computing device 12 may include an ink rendering module 32 configured to display the selected item 28 as part of a selected journal page graphic 31 as a marked-up journal page graphic. The ink rendering module 32 may also provide the user with selectable choices, such as line type, line width and line color.
A data-holding subsystem may be operatively coupled with the touch sensitive display 14 and may be configured to hold a plurality of journal page graphics. The plurality of journal page graphics may be a plurality of hierarchically flat sequentially arranged journal page graphics 70 discussed below. An analog input module 34 may be included in the data-holding subsystem, and may be configured to cause the marked-up journal page graphic to be saved in the mass storage 36. A page module 33 may provide additional journal page graphics 31, and/or may order the journal page graphics 31.
The computing device 12 may also include an aging module 40 operatively coupled with the touch sensitive display 14 and the data holding subsystem. The aging module may provide what may be referred to as paper physics. The aging module 40 may be configured to display each of the journal page graphics 30 on the touch sensitive display 14 as a paper page from a paper journal. The aging module 40 may be configured to selectively control display of aging characteristics to the journal page graphic 31. The aging characteristics may be variably applied. The aging characteristics of each journal page may be based on at least one of an age of such journal page and an amount of usage associated with such journal page. In some examples, the selected journal page graphic 31 may be configured to change appearance in accordance with one, or both, of an elapsed time from a creation of the selected journal page graphic 31, or a cumulative duration of a time since the journal page graphic received a first touch input 16. A clock/calendar module 42 may provide a measure of the duration of time.
The architecture 10 may also be configured to execute various other applications 50. The other application 50 may be executable upon recognition of other predefined gestures. As an alternative to, or in addition to, using gesture recognition to execute the various other applications 50, or to apply one or more selected items 28 on the touch sensitive display 14 to a selected one of the plurality of different PIM schemas 30 as described, various command buttons 52 may be used. The various other applications 50, and or the applying of different PIM schemas 30 may also utilize a search module 54. The search module 54 may be coupled with, or able to be coupled with, a computer network 56, such as, for example, the Internet.
In addition, the architecture 10 may include a location module 58 coupled with, or able to be coupled with, a GPS system 60. A particular location where a user was located when a particular touch input 16 was made may be saved in the PIM database 26, and or the mass storage 36. The location of the computing device 12 when an input was made, may then later, be included as part of various search criteria that may be used to recall an item included in a PIM schema 30. In addition, or alternatively, the location of where any particular touch input 16 was made, whether part of a PIM schema 30 or not, may be used to locate a particular journal page graphic 31. This may be useful, for example, if a user is able to remember where they were when an input was made, such as on a trip, or at a meeting, but can not find the particular journal page. This may be akin to helping a user find a particular one page in a large paper journal based on the user's memory of where they were when they wrote down, or sketched something, but would otherwise have to thumb through most, or all of the paper journal to find it. In addition, or as an alternative, to using geographic cues to find a particular journal page, the user of the computing device 12, described herein, may use various other sensory cues such as the age, and/or general appearance of a journal page graphic 31. The architecture 10, computing device 12, and methods, described herein may be configured to provide these sensory cues.
Fig. 2 is a schematic illustration of a computing device 12 that may be used for receiving and saving analog input from an input device 17, and/or digital input. Fig. 3 is a schematic view illustrating a plurality of hierarchically flat sequentially arranged journal pages 70. The computing device 12 may include a user interface 19 configured to selectively display the plurality of hierarchically flat sequentially arranged journal pages 70 on a touch sensitive display 14. One journal page graphics 31 is shown in Fig. 2. The user interface 19 may be configured to apply a selected item 28 on a selected one of the journal page graphics 31 to a selected one of a plurality of PIM schemas 30 in response to a touch input 16 applied to the touch sensitive display 14. This may occur upon recognizing a predefined freeform gesture, as a recognized gesture 23, made with the input device 17. The computing device 12 may include an aging module 40 (Fig. 1) configured to control aging appearance characteristics for each touch input 16 applied to the touch sensitive display 14. Each of the journal page graphics 31 may be configured to appear on the touch sensitive display 14 as a paper page from a paper journal. The aging module 40 may be configured to redisplay selected journal page graphics 31 at one or more later times with predetermined graphical modifications 72 according to predetermined temporal conditions and/or predetermined use conditions. The predetermined graphical modifications 72 may be included as sensory cues to enhance the journaling experience, and as aids to recall, as discussed.
The selected journal page graphic 31 may be configured to change appearance, i.e. with the addition of the predetermined graphical modifications 72, in accordance with one, or both, of an elapsed time from a creation of the selected journal page graphic, or a cumulative duration of a time that the journal page graphic has been selected among the plurality of hierarchically flat sequentially arranged journal pages 70. The predetermined temporal conditions may include a duration from a first use of the selected one of the journal page graphics, and the predetermined use conditions include a can amount of use incurred by the selected one of the journal page graphics.
The use module 40 may be configured to add an appearance of one or more of discoloration such as yellowing, smudges, crinkles, wrinkles, rips, smudges, soil marks, and folds to the selected journal page graphic 31 in accordance with the cumulative duration as the selected journal page graphic 31, and/or a cumulative amount of analog input having been made to the computing device while the journal page graphic is the selected one of the journal page graphics 31.
In some cases, upon recognizing a predefined freeform gesture 23, the user interface 19 may cause one of a plurality of overlay navigational tools to be displayed on the touch sensitive display 14 to help a user navigate the possible actions and reactions of the computing device 12 by verifying its' occurrence. The gesture recognition module 20 may be configured so that upon determination of the recognized gesture 23, the gesture recognition module 20 may causes the touch sensitive display 14 to display verification 80 of the application of the selected item to the selected one of the plurality of PIM schemas. After a preselected time, for example one second, of being visible on the touch sensitive display 14, the verification 80 may disappear. The verification 80 may take various forms, for example a box with a label corresponding to the PIM schema. A navigation arrow 82 may also be included with the verification 80.
In some cases the plurality of hierarchically flat sequentially arranged journal pages 70 may be advanced, or reversed, or otherwise scrolled backward and forward. In some cases this may be accomplished by running a users finger, or another type of input device in an upward or downward direction as illustrated with arrow 90 at location 92. Other activation techniques may be used. The activation techniques may be referred to as a scroll page gesture.
Fig. 2 illustrates an analog input area on a right side 94 of the computing device 12, and various other features on a left side 96. This is an example configuration. In some cases both sides may be configured for analog input. In some cases the left side 96 may be configured for analog input and the right side 94 may be configured to display other features. Left side 96 analog input may be the preferred configuration for a left handed person, and vise versa. The computing device 12 may include a spine 98 between the left side 96 and the right side 94. The computing device 12 may be foldable at the spine similar to a paper journal. An example command button 52 is illustrated on the spine.
The various other features on the left side 96 of the journal structure illustrated in Fig. 2 may enable various other functions besides those discussed in detail herein. Various features may be, for example selectable icons may be made selectively visible, and may be scrollable. Fig. 4 is a schematic illustration of an example architectural structure 100. The architectural structure 100 illustrates icons that may be selectable to, for example, enable various PIM schemas 30, various other applications 50, or other schemas. In addition, various notebooks, each containing various number of displayable journal page graphics 31 may be selected , by selecting corresponding icons, which may then make the selected notebook visible on the touch sensitive display 14.
Fig. 5 is a flowchart illustrating an embodiment of a method 200 for receiving and processing touch inputs in a computing device. Method 200 may be implemented using systems and devices described above, or using other suitable hardware and software. The method 200 includes, at 202, receiving a touch input at a touch sensitive display. The touch input may be from an input device made on a surface of a touch sensitive display of a computing device. At 204, the method may also include recognizing a predetermined gesture made on the surface as a request to save the touch input into a searchable database. Step 204 includes determining, based on the touch input and by selecting from a plurality of different predefined gestures, a recognized gesture that corresponds to the touch input. The method includes applying a selected item shown on the touch sensitive display to a selected one of a plurality of PIM schemas, the selected one of the PIM schemas being selected based on the recognized gesture. At 206, the method also includes recognizing alphanumeric characters made with the touch input at least upon recognizing the predetermined gesture. At 208, the method also includes saving the alphanumeric characters into the searchable database as a searchable item, e.g. one or more of a task item, a calendar item, and a contact item. At 210, the method may also include displaying a journal page graphic on the interface surface, to appear as paper journal page from a paper journal. At 212, the method may also include saving the pen stroke input as a simulated writing implement marking on the journal page graphic. In addition, and 206, the method may also include modifying the appearance of the journal page graphic in accordance with preselected aging, and/or use criteria.
Fig. 6 is a flowchart illustrating an example variation of the method 200 shown in Fig. 5. The method 200 may further include at 216, selectively displaying additional journal page graphics upon receiving a scroll page gesture from the input device on the interface surface. In some cases the additional journal page graphics are from the plurality of hierarchically flat sequentially arranged journal pages 70 shown in Fig. 4.
Fig. 7 is a flowchart illustrating another example variation of method 200 shown in Fig. 5. The modifying the appearance 214 (Fig. 5) may include, at 218, adding a color to the journal page graphic to give the journal page graphic a yellowing appearance in accordance with an elapsed time from when the journal page graphic received a first touch input.
Fig. 8 is a flowchart illustrating another example variation of the method 200 shown in Fig. 5. The modifying the appearance 214 (Fig. 5) may include, at 220, adding graphical features to the journal page graphic that appear as one or more of crinkles, smudges, wrinkles, rips, and soiling in accordance with a cumulative duration of a time the journal graphic has been displayed, and/or a cumulative number of touch inputs received on the surface of the touch sensitive display.
